I remember HairLossTalk.com posting "For people with acne it can be good for your sking, but for peopel with perfect skin it completely dries it out"
I also remember one of the many posters who complained about finasteride causing acne saying "After I realised the acne was giving me scars, i dug around, and it seems like people who get acne from propecia pretty much have a permanent problem with it"
Everyone is different.
